Limit SSID Broadcasts with WCS or WLC

Unanswered Question
Apr 7th, 2008

Is it possible to limit which SSID's particular AP's broadcast? I've tried using AP Groups, but that only segments the VLAN broadcast domain. The AP still broadcasts all SSID's. I have 2 APs in a jury waiting room - I only want to broadcast their SSID, not the all the others (confusing for them). Does anyone know how to do this? We're using a 4400 series WLC in this building and version 5.0.56 of WCS.

I have this problem too.

Hi Bill,

You will want to look into this.The feature you are looking for is called WLAN Override :)

Enabling WLAN Override

By default, access points transmit all defined WLANs on the controller. However, you can use the WLAN Override option to select which WLANs are transmitted and which ones are not on a per access point basis. For example, you can use WLAN override to control where in the network the guest WLAN is transmitted or you can use it to disable a specific WLAN in a certain area of the network.

From this doc;

Once you create a new WLAN, the WLAN > Edit page for the new WLAN appears. In this page you can define various parameters specific to this WLAN including General Policies, RADIUS Servers, Security Policies, and 802.1x Parameters.

**Check Admin Status under General Policies to enable the WLAN. If you want the AP to broadcast the SSID in its beacon frames, check Broadcast SSID.

Note: You can configure up to sixteen WLANs on the controller. The Cisco WLAN Solution can control up to sixteen WLANs for Lightweight APs. Each WLAN has a separate WLAN ID (1 through 16), a separate WLAN SSID (WLAN name), and can be assigned unique security policies. Lightweight APs broadcast all active Cisco WLAN Solution WLAN SSIDs and enforce the policies that you define for each WLAN.

From this good doc;

The most popular way to mitigate the problem of having to access each AP individually (when using WLAN Override) is to use WCS Templates for common requirement AP's. This way the WLAN Override function can be applied at the Template level and then pushed out to the various groups.

Hope this helps!
